Problems solved by technology

Due to the different spectrums of different white LEDs, the color of the coated color chip will also be different. Among them, when the coating error of some wavelengths is large, especially when the color of the coated color chip is a composite color of cyan and red, it is more difficult. Realize the consistency of the color of the coating chip

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a method, medium and equipment for selecting consistent color chips of white light LED lamps. Background technique [0002] With the emergence of LED, because of its high luminous efficiency and low price, it has been widely used in various signal display and lighting source fields, such as automobile interior and exterior lights, various traffic lights, etc., among which the application of colored lights is more common . When white LED products need to use color, they use coated color chips to filter part of the spectrum to achieve color effects. Due to the different spectrums of different white LEDs, the color of the coated color chip will also be different. Among them, when the coating error of some wavelengths is large, especially when the color of the coated color chip is a composite color of cyan and red, it is more difficult. To achieve the consistency of the color of the c...
